Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a drying device for sewage treatment. Background Art

[0002] Sludge is a solid sediment produced by the water and sewage treatment process. The sediment with organic matter as the main component is called sludge, and the sludge drying device for sewage treatment can dry the sludge.

[0003] At present, a Chinese patent with announcement number CN 109539703 B discloses a novel material drying device, in which a solution concentration system adopts a heat pump vacuum low-temperature evaporation technology to form a concentrated solution. The concentrated solution undergoes heat and mass exchange with the wet air generated by the material drying system through a solution sprayer in the solution dehumidification system to form a dilute solution. The dilute solution is collected and flows into the solution concentration system for concentration to form a concentrated solution. The wet air becomes high-temperature dry air. The high-temperature dry air enters the air supply port under the action of a circulating fan to dry the dried object, thereby achieving material drying.
